摘要： A reading assembly includes a stimulating light beam system having a plurality of laser diodes and a CCD line sensor having a plurality of CCDs. The laser diodes and the CCDs are disposed in a predetermined range of distances from the stimulable phosphor sheet along a main direction in order to cope with a deformation of the stimulable phosphor sheet in the main direction.

摘要： Stimulating light is projected onto a stimulable phosphor sheet while the image read-out mechanism is being moved in a sub-scanning direction relatively to the stimulable phosphor sheet and stimulated emission emitted from the stimulable phosphor sheet upon exposure to the stimulating light is detected by the photoelectric converter. The image read-out mechanism is moved back and forth in the sub-scanning direction. First and second image signals are obtained on the basis of the stimulated emission detected during the forward and backward movements of the image read-out mechanism, and an image signal representing the radiation image on the stimulable phosphor sheet is obtained on the basis of the first and second image signals.

摘要： A reading unit has an auxiliary scanning feed mechanism for feeding a stimulable phosphor sheet vertically in an auxiliary scanning direction, a laser beam applying mechanism for applying a laser beam substantially horizontally to the stimulable phosphor sheet and scanning the stimulable phosphor sheet with the laser beam in a main scanning direction, a reading mechanism for photoelectrically reading radiation image information carried by the stimulable phosphor sheet, and a sheet holding mechanism for holding opposite surfaces of the stimulable phosphor sheet to prevent the stimulable phosphor sheet from being unduly displaced transversely back and forth in the beam applying position. A scanning apparatus which incorporates the reading unit is relatively simple in structure, small in size, and allows high-quality radiation image information to be read from the stimulable phosphor sheet.
